2 / 13 page STCC02-ED5 2/13 Figure 2: STCC02 Based Application Diagram Figure 3: Circuit Block Diagram FUNCTIONAL DESCRIPTION The STCC02 is a control circuit embedding most of the analog & power circuitry of a microwaves oven control module. It interfaces the micro-controller with the power and process sections of the oven. ■ The voltage supply The 5V voltage regulator supplies the micro-control- ler MCU: especially functions such as the timer, the Analog-Digital Converter ADC, and the low current outputs. Since all the high-current outputs sink their current from a different voltage supply, this regula- tor does not need to be oversized. Its average out- put current can vary from 5 to 20 mA.
